Title: Electromagnetic Design by Inverse Maxwell Solvers
Abstract: How do we co-optimize millions of geometrical parameters which define an optimal electromagnetic design? Fortunately, elegant mathematical methods have emerged that require only two solutions of Maxwell’s Equations in standard solvers to optimize a complex geometry. The mathematical approach is called the “Adjoint Method”, and it relies on the chain rule of calculus.

Photonic inverse design uses advanced computational methods to find optimal photonic device geometries. Designers can generate optimized devices that can be manufactured with standard photolithography techniques. Ansys’ Inverse Design workflow combines Ansys’ gold-standard Lumerical FDTD simulator with an open-source implementation of the continuous adjoint method, lumopt.
Join our workshop where we will perform inverse design using the adjoint optimization method to design a robust, small footprint y-splitter. Learn how to leverage a workflow combining Lumerical FDTD simulator and lumopt to design a y-splitter that can be easily manufactured and measured. The workshop will also discuss the use of open-source layout tool KLayout.
